1 Samuel 16:2-5

16:2 Samuel replied, “How can I go? Saul will hear about it and kill me!” But the Lord said, “Take a heifer with you and say, ‘I have come to sacrifice to the Lord.’ 16:3 Then invite Jesse to the sacrifice, and I will show you what you should do. You will anoint for me the one I point out to you.”

16:4 Samuel did what the Lord told him. When he arrived in Bethlehem, the elders of the city were afraid to meet him. They said, “Do you come in peace?” 16:5 He replied, “Yes, in peace. I have come to sacrifice to the Lord. Consecrate yourselves and come with me to the sacrifice.” So he consecrated Jesse and his sons and invited them to the sacrifice.
